CRUSHlNG-ROLL.

SPECIFICATION forming part of4 Letters Patent No. 606,234, dated J une 28, 1898'. Application filed April 24, 1897. SerialrNo. 633,691. (No model.)

To all whom it may concern: v

Be it known that l, ALFONSO PESANT, of the city of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Rolls, of which the following is a specification.

The present invention relates to a new and im proved roll.

In the drawingl have illustrated my invention as applied to a roll for crushing cane or similar material.

In said drawing, 1 represents the roll-shaft, which is provided with sections 2, 3, and 4, the sections 3 and 4 being of an increased diameter over their respectively preceding section, and each of said sections 2, 3, and 4 is made tapering. The section 4 is provided with feathers 5, adapted to engage in the cut-out portions in the roll-cylinder placed thereon.

6 designates an annular ring against which the end of the roll-cylinder abuts, said ring being made either integral with the shaft l or shrunk thereon. Y

7 designates the roll-cylinder, which is provided with teeth 8, which are here shown as zigzag. The shaft l is provided with cutfout portions 9, and registering therewith are cutout portions 10 in the roll-cylinder. The roll-'- cylinder 7 is placed upon the shaft l and is forced up into engagement with the sections 2, 3, and 4 by hydraulic pressure, the feathers 5 engaging feather-ways 1l, formed in the roll-cylinder. A

l2 designates a ring which is shrunk or screwed on the shaft l after the roll-cylinder is placed in position to retain the same in place, the said ring being shown in the drawing as shrunk on the shaft.

The advantage in providing the shaft with sections differing in diameter is that the rollcylinder `may be forced thereon and a tight t secured. When the roll-cylinder is placed` upon the shaft, the sections of larger diameter pass over the sections of smaller diameter until the rollis nearly in position. Pressure is then applied to it, and the corresponding sections come in contact with each other, and a tight tis secured where necessary in every part of the shaft. The object in providing cut-out portions 9 and l0 in the shaft and cylinder is that by so doing the manufacture of the roll is made easier. It is difcult to secure a tight lit between a long conical shaft and cylinder, but the cut-out portions divide the roll into sections in 'each of which a close t is secured, the contact between the different sections being sufficiently maintained for the purposes of the roll.

What is claimed as new isl. A roll consisting of a shaft having sectionsof differing diameters, a roll-cylinder having sectionsof corresponding different diameters mounted thereon, and means for securing the roll-cylinder to the shaft, substantially as specified.

I 2. A roll consisting of a shaft provided wit-h sections of differing diameters, each of which is tapering, a roll-cylinder having sections of corresponding different diameters mounted thereon, and means for securing inder to the shaft, substantially as specified.

In testimony whereof I have signed my name to this specification in the `presence of two subscribing witnesses.

ALFONSO PESAN'T.
